Very Wideband, Low Distortion Triple Video Buffer
LMH6739
Very Wideband, Low Distortion Triple Video Buffer
General DescriptionThe LMH6739isa very wideband, DC coupled monolithic
programmable gain buffer designed specificallyfor ultra high
resolution video systemsas wellas wide dynamic range
systems requiring exceptional signal fidelity. Benefiting from
National’s current feedback architecture, the LMH6739of-
fers gainsof −1,1 and2.Ata gainof+2 the LMH6739
supports ultra high resolution video systems witha 400 MHz
2VPP3dB Bandwidth. With 12-bit distortion level through30
MHz (RL= 100Ω), 2.3nV/ input referred noise, the
LMH6739isthe ideal driveror bufferfor high speed flash A/D
and D/A converters. Wide dynamic range systems suchas
radar and communication receivers requiringa wideband
amplifier offering exceptional signal purity will find the
LMH6739’s low input referred noise and low harmonic dis-
tortion makeitan attractive solution. The LMH6739is avail-
ableina space saving SSOP package.
Features 750 MHz−3dB small signal bandwidth (AV= +1) −85 dBc3rd harmonic distortion (20 MHz) 2.3 nV/ input noise voltage 3300 V/µs slew rate32 mA supply current (10.6 mAperop amp)90 mA linear output current 0.02/0.01 Diff. Gain/ Diff. Phase (RL= 150Ω) 2mA shutdown current
Applications RGB video driver High resolution projectors Flash A/D driver D/A transimpedance buffer Wide dynamic rangeIF amp Radar/communication receivers DDS post-amps Wideband inverting summer Line driver
